Little bent-wing bat

Miniopterus australis

The little bent-wing bat is the smallest of all the bent-wing bats. It has chocolate brown fur all over, that is lighter on its belly, and it has a short muzzle and domed head. These are cave dwelling bats but have been known to utilise abandoned mines, tunnels, stormwater drains and occasionally buildings.


Little bent-wing bats prefer well timbered areas where they feed primarily in the shrub and canopy layers. Their diet consists primarily of beetles, moths, flies and even spiders. Little bent-wing bats congregate in maternity colonies during summer and populations can get up to 100,000 individuals.


Females congregate in maternity colonies with the eastern bent-wing bat from August. Young are born in December.
